What is the bladder capacity of 6-year-old children?

The bladder capacity of a 6-year-old child is generally about 210ml.

Usually, because the child's body is immature, the organ tissue is usually smaller than that of an adult, so the child's bladder capacity is also smaller than that of an adult. According to the calculation formula of the child's bladder capacity: bladder capacity (ml)= age (years)*30+30, the child's bladder capacity can be predicted, so for a 6-year-old child, the bladder capacity is approximately 210ml. However, due to different growth and development of children, different weight, etc., may lead to a certain difference between the actual volume of the bladder and the expected value, but as long as the child urinates normally, there is generally no need to worry too much.
